UNITED STATES PATENT OFFICE.

EDOUARD VEDOVELLI, OF PARIS, FRANCE, ASSIGNOR TO HENRY GUINARD,

OF NEW YORK, N. Y.'

ELECTRIC-LAMP SHADE.

SPECIFICATION forming part of Letters Patent No. 528,241., dated October30, 1894.y

Application Elea August 4, 1894.

To @ZZ whom it may concern,.-

Be it known that I, EDOUARD VEDOVELLI, a citizen of the Republic ofFrance, and a resident of Paris, France, have invented certain new anduseful Improvements in Electric- Lamp Shades, of which the following isaspeciiication.

This invention relates to a shade for incandescent electric lamps, whichis provided with an endless 'adjustable clasp at its lower` end. Thisclasp is expanded when the shade is slipped over the bulb of the lamp,and is then contracted, to tightly embrace the neck of the lamp.

The advantages of my construction are that no springs or catches arerequired, and that the clasp will readily adjust itself to lamp necks ofdifferent sizes.

In the accompanying drawings: Figure 1 is a side elevation, partly insection, of my improved electric lamp shade. Fig. 2 is a cross sectionon line 2,2, Fig. 1.

The letter a, represents a series of longitudinal wires connected, ifdesired, on top to the cross Wires a', and forming a eXible skeletonthat surrounds the bulb A, of the electric lamp. Upon the Wires a, a',are strung glass beads or prisms c,which are made of suitable design andcolor, and cover the wires from end to end. To the lower ends of thelongitudinal wires 0 there is secured an annular clasp b, which is soconstructed that it may be readily distended or contracted. To this eectthe clasp b, consists of two intersecting series of pivotally connectedlinks that operate in the manner of lazy-tongs.

Serial No. 519,430. (No model.)

One series of these links projects slightly above the other series, toconstitute perforated lugs, to each one of which, one of thelongitudinal wires ct, is attached. Thusl 1t will be seen, that theclasp may be readily expanded when the shade is slippedover the bulb ofthe lamp, and may as readily be contracted around the neck of the lamp.Moreover the expansion and contraction of the clasp will correspondinglydiverge or converge the lower ends of the longitudinal w1res so thatsuch wires will adapt themselves to the altered diameter of the clasp,and still retain a uniform distance from one another.

What l claim is- 1. An electric lamp shade consisting of a series oflongitudinal wires, beads strung thereon, and of an endless expansibleclasp composed of two series of intersecting pivoted links,substantially as specified.

2. An electric lamp shade consisting of a series of longitudinal wires,beads strung thereon, and of an endless expansible clasp composed of tWoseries of intersecting pivoted links, all being so constructed that oneseries of said links is provided with upwardly projecting perforatedlugs, to which the longitudinal wires are secured, substantially asspecied.

Signed at Paris, France, this 16th day of June, A. D. 1894.
